I understand this is quite a complicated title, however I have failed to discover a word (or a few words) to adequately describe the creative language used when changing a saying (or well-known phrase) into something slightly different, with a different meaning but still echoing the original phrase used.
As much as that was a horrible way of trying to explain the concept, I will provide an example that expressed want I want to sufficiently and coherently explain.
A reasonably well-known phrase which was used on a recent Batman film by Christopher Nolan (although this won't have been the first use of the phrase) is:
Some people just want to watch the world burn
Recently, I came across this photo which was a very clever (in my opinion) use of that phrase, changing it slightly to give it a different meaning based upon the current situation:
Some thugs just want to watch the world learn [see photo below]
Which is very clever and I was wondering if there is a word that describes the creative language used here.
Any insight would be much appreciated.
